JavaScript High Performance focuses on making your JavaScript code run more efficiently, raising your app performance. ECMAScript 6 (ES6) is the new step to the ECMAScript language, whose specifications are inherited by JavaScript. ES6 gives a vast makeover to JavaScript by adding new syntaxes and APIs to write complex applications and libraries that are easier to debug and maintain. ES6 aims to keep JavaScript accessible for casual developers, even after adding new advanced features.

To begin with, you will get familiarized with Babel.js, which will help you use the latest features of ES6 in all browsers. You’ll gain a concrete understanding of ES basics and classes, modules, inheritance, as well as the coding style. You’ll build your skills with recommended code organization patterns in JavaScript, making your code easy to organize.

Moving on, we’ll discuss advanced features such as collection types, template literals, and symbols. Next, you’ll see how to use tools to write asynchronous code much better with promises and asynchronous functions. Lastly, we will deal with some experimental proposals and references. By the end of the course, you will understand how ECMAScript is going to be the new paradigm.
